Running in oil

Gostek

I was scanning ebay for some running in oil in 20l barrels as I'll need it for mine and mates car (3 oil changes each makes sense to buy 20l) and I've come across this http://www.ebay.co.uk/itm/RUNNING-IN-OIL-API-CC-SE-20-LITRES-FOR-BEDDING-IN-REBUILT-ENGINE-COMPONENTS-/290637662117?hash=item43ab5ac7a5:g:gCkAAOxy43FRZr0h

I was wondering what you guys think about it. Price doesn't look too bad and we're using Exol at work (it goes in to Sprinters and Actroses).Or shall I just get barrel of 15w40?
